Which of the following electron configurations is correct for oxygen (atomic number 8)?
- A 1s2 2s2 2p2
- B 1s2 2s2 2p3
- C 1s2 2s2 2p4
- D 1s2 2s2 2p5
That's Correct!
It's Wrong!
The correct electron configuration for oxygen (atomic number 8) is '1s2 2s2 2p4'. Oxygen has 8 electrons, and following the Aufbau principle, we fill the lowest energy levels first, with the s orbital being filled before the p orbital. Each orbital can hold a maximum of 2 electrons, and thus, the p orbital will be filled with 4 electrons.
